Bouquet, F

A summary of the technology for evaluating reflective surfaces for parabolic solar dishes is presented. Commercial, second-surface glass mirrors are emphasized, but aluminum and metallized polymeric films are also included. Criteria for sealing solar mirrors in order to prevent environmental degradation and criteria for bonding sagged or bent mirrors to substrate materials are described. An overview of the technical areas involved in evaluating small mirror samples, sections, and entire large gores is presented. The objective of this study is to establish a basis for mirror criteria that eventually may become part of inspection and evaluation techniques for three-dimensional parabolic reflective surfaces. Concentrator support structure, optical tracking, gore alignment, and other important ancillary problems are omitted from this study. A glossary and important references concerning optical criteria are included.
